I read some where that the grizzly looks like the bug moving its wings and i mostly use the regular grizzly. half of this is maybe because all i have is brown grizzly, and a sand color, but i believe half is true. But i voted grizzly.
Look through your local fly shop, some times you find a good deal. Once, i got a good quality cape for 20 bucks which isnt too bad considering some go for 90.
